RenderTexture on GUI crashes application

Hello guys.

I am currently trying to convert my camera handling system to the Vita, but it seems like no matter what i try, the application crashes whenever i try to send a RenderTexture to the GUI.

Code like this seems to work on PC, but i cannot seem to figure out why this cannot work on the Vita:

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class SimpleRenderTex : MonoBehaviour
5. {
6.     private RenderTexture renderTex;
7.     private Rect viewRect = new Rect(0,0,Screen.width,Screen.height);
8.    
9.     void Start ()
10.     {
11.         renderTex = new RenderTexture(128,128, 24, RenderTextureFormat.RGB565);
12.         renderTex.Create();
13.        
14.         camera.targetTexture = renderTex;
15.     }
16.    
17.     void OnGUI()
18.     {
19.         GUI.DrawTexture(viewRect, renderTex);
20.     }
21. }
22.  

Now, the problem does not seem to be in the actual GUI aspects of things since it will still crash without the GUI.DrawTexture aspects included, so i will assume that the main problem is when the system creates the 128x128, 24 bit rendertexture. Rendering from camera to a rendertexture in the editor does seem to work, but i cannot seem to get it to work from code.

 

Try a different render texture format. There should be some more examples on the wiki.

Code (csharp):

1. 16,16, TextureFormat.RGB24
2. 4, 4, TextureFormat.DXT1

Also try this, theres a render textures support option at bottom:

Code (csharp):

1. function ShowDevice() {
2.     GUILayout.Label ("Unity player version "+Application.unityVersion);
3.     GUILayout.Label("Graphics: "+SystemInfo.graphicsDeviceName+" "+
4.     SystemInfo.graphicsMemorySize+"MB\n"+
5.     SystemInfo.graphicsDeviceVersion+"\n"+
6.     SystemInfo.graphicsDeviceVendor);
7.     GUILayout.Label("Shadows: "+SystemInfo.supportsShadows);
8.     GUILayout.Label("Image Effects: "+SystemInfo.supportsImageEffects);
9.     GUILayout.Label("Render Textures: "+SystemInfo.supportsRenderTextures);
10. }

 

Thanks Jesus, i will try this out.

 

Just tested the show device info on mine..
Graphics PSVita GXM 104mb
Says shadows, effects and render textures do not work, but they do as I've got render to textures and shadows haha

So ignore the device info, its wrong, but still try out the different texture formats, link here.

ARGB32 seems to work pretty okay for me, but i will have to see if other formats work better. Thanks for the help!
